According to get_current_screenDocs:

it'll "return current screen object or null when screen not defined".

If you want to use it to detect admin pages, then use a different hook, for example you could use current_screen hook:

add_action('current_screen', 'detecting_current_screen'); function detecting_current_screen() { $current_screen = get_current_screen(); print_r($current_screen); } 

Or

add_action('current_screen', 'detecting_current_screen'); function detecting_current_screen() { global $current_screen; print_r($current_screen); } 

If you want to use it on the client-side and that returns null, then you could use a global variable called $pagenow.

Note: $pagenow will give you the template name.

global $pagenow; echo $pagenow; 

Or

echo $GLOBALS["pagenow"]; 

This should give you the name of the template you're on:

add_action( 'wp_footer', function () { global $pagenow; echo $pagenow; }, 999 ); 

If none of the methods, mentioned above, work for you, then you could use another global variable called $post.

Or

You could check your page by using:

get_page_by_titleDocs
or
get_page_by_pathDocs
